Bernard,

Here's some pics and info for you to look over :)

Big fan of the spiro's like Stewart mentions, my first one was the Tag Heuer version, had a Auricoste at some time in my hands and two Doxa versions, the first one i stupidly sold and it was almost perfect condition. Last year i searched for a replacement, they ain't easy to find now thats for sure.

I know Stewart and Dave have the Tag versions and i believe Jeff Stein has the Triton Spirotechnique ;)

The Doxa i got recently needed a lot of tlc, i had to do a full restoration on it, all the details can be found here - http://forums.watchuseek.com/f34/doxa-spirotechnique-600t-questions-restoration-1000646-post7539961.html

Way back in 2010, i did a small post regarding ebay spirotechnique fakes, yes they existed, hopefully you can view the post over at TZUK - http://forum.tz-uk.com/showthread.php?126262-Spirotechnique-Fakes&highlight=doxa+spirotechnique

There were a lot of watches using similair cases, Dodane, Sinn, and prob the most sought after which is the Squale version, never came across or had the chance to buy one but i certainly would, its a beauty :)

Best,

James.
